Sorry to hear about your baby. First time I hear a dog having asthma, there's always a first ,huh? What did the vet say to do or not do do? Any medications? What were the symptoms? Sorry for so many questions, I grew up with my father, brother and sisters with asthma attacks and it's no funny joke. It's the worse feeling a human being has when you cannot help that person to breath.
Hope eveything works out for you and your baby.
